I haven’t collected buttonbush seeds in many years. Most people prefer to purchase already grown shrubs and it is understandable. However, after seeing how nice and floriferous a small group of buttonbushes were looking despite the terrible drought, I had a change of heart. After all, most sources indicate that it is an easy to germinate species.
Cephalanthus occidentalis is a deciduous shrub with a rounded, open habit that can reach 3+ m (in optimal conditions), ie. wetlands, ponds and lakes edges, other wetland habitats. The more moisture it gets the larger it will grow.
The Buttonbush takes its common name from the round flower heads formed from many, small tubular flowers with exerted stamens. They flower gradually over a long period and are very fragrant! They attract many insects, especially long-tongue pollinators like bumblebees, butterflies, hummingbirds. The buttonbush is also a ‘honey plant’.
The fruiting heads take an attractive red color in late fall before seeds maturation; the fruits are 2-seeded nutlets (used as food by various waterfowls). So, it is one of those cases when we are actually sowing fruits, not seeds.
Good news is that the Buttonbush adapts well to growing in regular garden soil, except very dry locations. It just won’t grow that tall, which is actually a good thing for our gardens.

Another species recently added to the inventory that also prefers wet places but grows perfectly well in regular soil isTeucrium canadense , the American germander.
Same like the Buttonbush, it performed well during a very dry season, so we shouldn’t be afraid to grow it. I failed to take a picture at its peak flowering time, but believe me that the long flower spikes (light to deep pink) are attractive and good for pollinators. It does well in sun to part-shaded locations; some also call it Wood Salvia.
Speaking about wetland species that perform very well in regular garden conditions, the Carex grayi seeds inventory has also been replenished.
For the last species, Wild Calla, we would really need a small pond or other water feature to be able to grow it. Calla palustris is a great addition to a wetland area due to its handsome foliage, long flowering period and bright, red fruits in the fall. Most years the fruits are hard to reach, so I took advantage of the receding water on the margin of a pond this fall; those interested can now grow their own wild ‘exotic’ Calla! The seeds are kept moist to ensure good germination.
